HitMe is a computer game built with an exceedingly minimal reward structure. A black square centered on a white screen expands slightly when the viewer punches the pad mounted below, swelling with repeated impacts, then slowly reducing in size when the contact stops. The idea of the piece was to construct a situation which would elicit violent behavior with little prompting, teasing out pleasure implicit in the violence of the act itself. I developed the hardware for this project using an Atmega AVR chip (Atmega32) programmed in C, a force sensing resistor (FSR), and graphics code written in Processing.
